Preface

This manual is a translation and adaptation of "La culture
mara," published by the Agri- Service- Afrique of the Institut africain
pour le dloppement nomique et social (INADES), and forms part of a series.
Grateful acknowledgement is made to the publishers for making available this
text, which it is hoped will find widespread use at the intermediate level of
agricultural education and training in English- speaking countries.

It should be noted that the original texts were prepared for an
African environment and this is naturally reflected in the English version.
However, it is expected that many of the manuals of the seriesa list of which
will be found on the inside front coverwill also be of value for training in
many other parts of the world. Adaptations can be made to the text where
necessary owing to different climatic and ecological conditions.

Applications for permission to issue this manual in other
languages are welcomed. Such applications should be addressed to: Director,
Publications Division, Food and Agriculture Organization of the United Nations,
Via delle Terme di Caracalla, 00100 Rome, Italy.
